From Wojciech Lewandowski, "Most recent changes to CameraPathEventHandler change path writing method. Now control points are written on the fly. But default stream precision is not adjusted as it used to and remains set to 6 digits (at least with VS 2008) so larger coordinates like positions on Earth Ellipsoid loose lots of fidelity. This patch fixes this issue.
